Guidance Regarding Affidavits Used in Conjunction with Mariner Credentialing

The Office of Merchant Mariner Credentialing has published CG-MMC Policy Letter 01-20. This policy letter provides guidance on the affidavits required with an application for a duplicate merchant mariner credential (MMC) and mariner medical certificate. In accordance with Title 46 Code of Federal Regulations 10.229 mariners who have lost their MMC or medical certificate may be issued a duplicate. Mariners applying for a duplicate credential must submit an affidavit describing the circumstances of the loss. Once an affidavit is submitted as part of an application it is evidence that the applicant is affirming that the information provided is true and correct. 

This policy is available on the Coast Guard Merchant Mariner Credentialing policy website. It may also be accessed by selecting “Policy & Regulations” on the National Maritime Center’s website.

Mariners and other interested parties should contact the Mariner Credentialing Program Policy Division at (202) 372-2357 or with any questions or feedback.
